VENTILATOR.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed May 24,1902. Serial No. 108,362-

To all whom it may concern:

Be it known that I, GILBERT F. WILLIAMs, a citizen of the United States, residing at "Washington, in the District of Columbia, have invented certain new and useful Impro vements in Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improvement in ventilators and it is embodied in the construction hereinafter described and defined in the claims.

The invention relates more particularly to that type of ventilator intended or designed for use in connection with vehicles such as cars, and also for houses, oflices and other compartments, wherein a fresh supply of air is needed.

An important requirement in ventilators for cars and all other ventilation, is to avoid blasts and prevent the entering of foreign matter such as rain, snow, hail or cinders, etc.

The present invention is intended to successfully fulfil this requirement, and also to provide a structure which will normally be 0 e11 to its full capacity, but which will be c osed or regulated as to its capacity automatically by the drafts or wind pressure in one direction so as to prevent direct drafts.

Therefore this invention consists in a pcculiarly constructed apparatus which will prevent blasts, and the ingress of rain, snow, hail cinders or other foreign matter carried by direct air currents, which will be so constructed as to permit the ingress of air without obstruction when air outside is in a static or quiet condition, that is no wind or forced movement of the air, which will be positioned either by being built into walls or placed in a window or other opening; which will be automatic in its adjustment; which in structure will embody simplicity, and which will be so shaped as to prevent the harboring of snow, hail, dirt, cinders etc.

In the accompanying drawings isv shown an embodiment of the invention in preferred and modified forms, but it is to be understood that the general principle of the invention. may be employed with apparatus of widely different forms and arrangement; therefore various changes and modifications of the invention shown can be made without departing from the nature and principle thereof.

Figures 1 and 2 are perspective views of the improved apparatus taken from opposite ends. Fig. 3 is a longitudinal vertical sec tion. Fig. 4 is a transverse section taken through the line 44 of Fig. 3. Fig. 5 is a. side view showing the inner hollow extension removed. Fig. 6 is a plan view showing the outer member removed, and Fig. 7 is a similar view of the inner member removed.

In the drawings A designates a casing which for convenience I have shown in cylindrical form, the same re resenting a drum. This drum or casing has formed an aperture in one Wall which is spanned by cross-bar B riveted or otherwise secured in position to an. extended flange a surrounding the said aperture. The flange a is provided convenientlyat diametrically opposite points, with studs.

or pins a and has an unobstructed outer end.

On the opposite, or what I will term the outer face a of the drum or casing A is formed an opening, hooded by a bracket A opening downward.

projected fixed hoods A as shown more par-. ticularly in Fig. 4. These hoods are con-. veniently and preferably made with openlower sides their outer ends, sides, and tops.

being closed so that any air entering into the ventilator presses up into the hoods and cinders, rain, snow etc., being deflected are prevented from entering through the opening A These hooded openings, may, if desired, be suitably screened, a feature which is not shown but which is obvious.

Located within the casing A is what I shall term an inner movable member or ele-. ment J which is of cylindrical formation and designed to fit within the casing and movetherewith in an oscillatory movement. The inner member is carried on the shaft D mounted on suitable pointed journal pins 0 which in turn are supported and carried respectively by the bracket A and the crosspiece B. The outer end of the shaft D. isprovided with a standard e'carrying a vane E which may be concavo-convex or rectangular and concaved on their outer faces as= shown in Fig. 2. The standard 6 is fixedlysecured to the shaft so that as the vane E is.- moved by the pressure of the air or the wind, the shaft D will be moved and will in turn move the inner member J. The inner member is provided with two openings J arranged opposite each other as shown in Fig. 4, the location of the openings being such as In opposite sides of the casing A are formed apertures A over which are to disclose both openings A when the vane E is in its normal position with its standard vertical. The openings J are in size sufiicient to permit the movement of the vane and the inner member to its full limit and still maintain the opening at one side in the casing fully disclosed, and at the same time the upper wall of the inner member is forced over the opposite opening thereby closing the same. By this means it will be observed that the normal condition of the ventilator is open held so by the weight of the vane and its standard and that by the movement of the vane E in either direction the opening in the direction of the direct draft or wind is closed while the opposite opening is opened thereby preventing the direct blast of wind entering the ventilator and thence into the compartment or room.

To permit the air to escape from the inner member through the opening in the outer member an opening is made in the inner face of the inner member which is spanned by a cross-bar J through which the shaft D passes. The air passing from the inner mem ber enters What I shall term the distributing portion of the ventilator, the same being represented as a drum or cylinder G, which has one end open, which end telescopes into or over the flange a as may be preferred. The edge of the member G is formed with a bayonet joint slot 9 into which the pins a are forced for locking the parts together; The cylinder G has an outer closed end G H represents an eXit opening from the top of the distributing member G and this opening is conveniently provided with a hinged closure H.

In operation it will be observed that normally there is a free access of air into the ventilator through the two openings A and thence into the member J from which the air issues through the opening J into the distributing member G, from whence it is permitted to escape through the opening H. Should there be any blast of wind blowing from the right of the ventilator, as represented in the drawing, the same would act against the vane E moving the same and cause the inner member J to move thereby closing the opening A on the side from which the wind comes, and permitting the opposite opening to remain open through which latter opening there will be What may be termed a counter current or movement of air into the ventilator and through the same and so without any rapid movement. This automatic action results in shutting off or preventing any direct blast entering the compartment irrespective of the wind force without. It has been found that by this arrangement a very perfect and satisfactory ventilation can be secured without the danger of drafts. Then it is desired to wholly close the ventilator it is only necessary to close opening H with or by the cover H. It will be observed that as the vane E is moved it should be limited in its movement to prevent the closing of either of the ventilating apertures or openings. To provide for this, suitable rubbered or other buffered pins 1) may be placed on the face plate of the casing A against which the standard will strike. In the application of the ventilator it is only necessary to remove the distributing member G and place the flange a within the opening formed in the carrier, either a sash, partition or structure, and the outer member may then be secured by any convenient means. Thereafter the inner distributing member can very readily be slipped over the flange and secured in place.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is 1. In a ventilator, the combination with a casing having an opening in its outer edge and an open side, of a flange surrounding said side opening, a support spanning said side opening, a shaft pivoted within the casing, and a removable extension on the side of the casing over the said side opening.

2. In a ventilator the combination with a casing having openings in its outer edges and an open side, a flange surrounding said opening in the side, a cross-bar spanning said side openings, a shaft pivotally mounted on the cross-bar, a cylinder mounted on the shaft within the casing having openings therein, a vane connected with said shaft, and a distributing member detachably con nected with said flange.
